How Can Consuming A Plant-Based Diet Reduce The Risk Of Cardiovascular Disease In Postmenopausal Women?, Rebecca Stack

Honors Program Theses and Projects

Despite the fact that women suffer higher rates of cardiovascular events after menopause, there exists a significant underrepresentation of women—especially postmenopausal women—in cardiovascular clinical trials to date. Fortunately, current evidence reveals that cardiovascular events in the general population are largely preventable through modifiable lifestyle factors, with dietary intervention being one of the most important (Amiri et al., 2022). As the impact of whole-diet interventions on cardiovascular risk factors is further explored, it has been determined that a plant-based dietary pattern may favorably influence the prevention of cardiovascular events in postmenopausal women (Barańska et al., 2021). Evidence also reveals that certain …

Comparative Analysis Of Longevity And Stress Resiliency Benefits Of Supplementation With High-Antioxidative Capacity Juices In Organisms That Are Representative Of Humans, Meghan Long

Honors Scholar Theses

Neurodegenerative disease presents itself in a complex array of illnesses that is increasingly affecting the geriatric population. There has not been research on a common cause since there are a culmination of reasons that are probable ranging from genetic to environmental factors. Antioxidants have been known to prevent and protect against the damage that is otherwise caused by reactive oxygen species (ROS). Thus, high-capacity antioxidant juices supplemented into the diet of animal models such as Caenorhabditis elegans, Drosophila melanogaster, rats, and humans will allow for the study of the possible benefits.

Although a conclusion and common causation on the usage …

Nutrition And Chronic Pain, Elise Withers, Mateja R. Savoie-Roskos, Riley Samples, Maren Wright Voss

All Current Publications

The internet is full of information about anti-inflammatory diets, foods, and supplements claiming to prevent or alleviate chronic pain. For those who struggle with chronic pain, sound dietary advice is essential to improve intake and ultimately decrease pain (Arranz et al., 2010). However, it’s important to note that research showing the impact of specific foods on health and the immune system is currently limited; therefore, these claims should be interpreted with caution (Elma et al., 2020; Harvard Health, 2018). This fact sheet will cover (1) how inflammation affects chronic pain and (2) how eating a well-balanced diet may help reduce …

Effect Of Whole Fruit Based Anthocyanins On Systemic Inflammation, Oxidative Stress, And Waist Circumference In Women, Anastasiya Yudinova

Cal Poly Humboldt theses and projects

Cardiometabolic disease (CMD) remains the leading cause of death nationally. Intra-abdominal fat (IAF) is one of the primary risk factors for CMD. Women are particularly vulnerable to developing CMD due to hormonal changes during and after menopause that increase IAF. Excess IAF has deleterious effects on the body, increasing systemic inflammation and oxidative stress, leading to CMD. This systematic review and meta-analyses examined current research related to consumption of whole foods high in anthocyanins, their impact on oxidative stress and inflammation, and the medium and amount of anthocyanin delivery that yields the most benefits to women at risk for CMD. …

The Effects Of Dietary Linoleic Acid And Hydrophilic Antioxidants On Basal, Peak, And Sustained Metabolism In Flight‐Trained European Starlings, Wales A. Carter, Kristen J. Demoranville, Barbara J. Pierce, Scott R. Mcwilliams

Biology Faculty Publications

Dietary micronutrients have the ability to strongly influence animal physiology and ecology. For songbirds, dietary polyunsaturated fatty acids (PUFAs) and antioxidants are hypothesized to be particularly important micronutrients because of their influence on an individual's capacity for aerobic metabolism and recovery from extended bouts of exercise. However, the influence of specific fatty acids and hydrophilic antioxidants on whole‐animal performance remains largely untested. We used diet manipulations to directly test the effects of dietary PUFA, specifically linoleic acid (18:2n6), and anthocyanins, a hydrophilic antioxidant, on basal metabolic rate (BMR), peak metabolic rate (PMR), and rates of fat catabolism, lean catabolism, and …

The Effect Of Sodium Selenate Biofortification On Plant Yield, Mineral Content, And Antioxidant Capacity Of Culinary Herb Microgreens, Rachel G. Newman

Graduate Theses, Dissertations, and Problem Reports

Selenium (Se) biofortification of plants has been suggested as a method for enhancing dietary Se intake. Popular herbs such as basil (Ocimum basilicum), cilantro (Coriandrum sativum), and scallions (Allium fistulosum) are used for enhancing flavors. Microgreens are young seedlings harvested with one to two true leaves and are increasingly popular in the consumer marketplace. In this study, basil, cilantro, and scallion microgreens were treated with various concentrations of Se as sodium selenate in hydroponic conditions to investigate the effect on plant yield, mineral content (selenium, sulfur, sodium, potassium, phosphorus, calcium, magnesium, copper, iron, manganese, zinc, and boron), total phenolic compounds, …

Understanding Lipid Oxidation In Low-Moisture Food, Leann M. Barden

Doctoral Dissertations

Low-moisture snacks account for much of the saturated fat in the diet, making them a key target for improving consumers’ health. However, it is not currently feasible to maintain the same shelf life when replacing saturated fats with unsaturated fats in these products. The first study characterized the microstructure of a low-moisture cracker model system and determined the impact of iron, chelators, and free fatty acids (FFA) on lipid oxidation kinetics. Confocal microscopy showed that lipids form a continuous layer surrounding the small and/or minimally gelatinized starch granules. Lipid-starch, lipid-air, and starch-lipid-protein interfaces all existed. Oxidation studies showed a large …

Honesty And Carotenoids In A Pigmented Female Fish, Alexandria Christine Brown

Doctoral Dissertations

The carotenoid tradeoff hypothesis states that diet-derived carotenoids are tradedoff among competing physiological demands, but this statement is rarely tested in ornamented females. The following dissertation tests the carotenoid tradeoff hypothesis in reverse sexually dimorphic convict cichlids (Amantitlania siquia) using carotenoidsupplemented diet treatments and a field-based study of carotenoid intake. Spectral, microscopic, and chemical analysis determined how females allocated the pigments to tissues and how those decisions affected their ventral patch coloration. The results presented in the current study show that carotenoids enhance offspring growth and survival, lower oxidative stress, and reduce the time to clear a parasite. The two …

Antioxidant Assessment In Western Maine Elderly Women Following 30 Days Of Wild Blueberry Consumption, John David Bagnulo

Electronic Theses and Dissertations

Increased fruit and vegetable consumption is the single most protective characteristic of a diet against disease. While the exact mechanism by which this protection is offered remains unclear, the leading theory is centered on the antioxidant content of fruits and vegetables. Recent studies have shown that certain fruits and vegetables have significantly higher antioxidant contents than others. Wild North American blueberries (Vaccinium angustifolium) have one of the highest antioxidant contents of all h i t s and vegetables tested. This thesis investigates the relationship between the consumption of blueberries and blood antioxidant levels in 24 elderly women. In addition, fruits …

Health-Promoting Properties Of Common Herbs, Winston J. Craig

Faculty Publications

Herbs have been used as food and for medicinal purposes for centuries. Research interest has focused on various herbs that possess hypolipidemic, antiplatelet, antitumor, or immune-stimulating properties that may be useful adjuncts in helping reduce the risk of cardiovascular disease and cancer. In different herbs, a wide variety of active phytochemicals, including the flavonoids, terpenoids, lignans, sulfides, polyphenolics, carotenoids, coumarins, saponins, plant sterols, curcumins, and phthalides have been identified. Several of these phytochemicals either inhibit nitrosation or the formation of DNA adducts or stimulate the activity of protective enzymes such as the Phase II enzyme glutathione transferase (EC 2.5.1.18).

Antioxidants And Alcohol In The Progression Of Acquired Immunodeficiency Syndrome, Laura Lynne Prestwich

Undergraduate Honors Capstone Projects

Wasting syndrome in acquired immunodeficiency syndrome (AIDS) appears to play a role in decline of immune function. Along with poor appetite, HIV infected individuals seem to have a tendency to be heavy alcohol drinkers which may be immunosuppressive and cause malnutrition. Altered macronutrient metabolism visibly contributes to wasting; however, micronutrient deficiencies also appear to play a role. Micronutrient deficiency has also been known to decrease immune function. As part of their role as antioxidants, P-carotene, vitamin C, vitamin E, and selenium may be helpful in altering cell production and response to cytokines and other secretions. This may decrease viral replication …
